Zoom / Camera Control in subplot

Ben — Mon, 17 Sep 2007 22:02:13 -0400

I have a GUI with one main plot axes (3-D) axes with a
couple small plots(2-D) and a few text boxes of data next to
it. My problem is that I need to Zoom in on a specific area
of the 3-D plot. However, I can not zoom in on the main
plot without the axes becoming larger than it was originally
defined as and overtaking the smaller plots.
I have tried using the camera commands (campos, camtarget,
va, ect.) and zoom and view commands. But when I zoom in on
the area I need it ends up dominating the entire figure window.

Is there a way to contain the axes so that it is limited to
only the position[l,b,w,h].

Any help or suggestions would be appreciated. I can provide
an example if needed.

Thanks

Here is an example. When the last line is executed the
second plot becomes to large and overlaps the top axis.
What I would like is for it zoom in on a region of the 3-d
plot, keeping the axes size/position the same. Not make the
axes larger. The only way I have been able to make this work
is to actually make a second figure and place it over the
first. There has to be a better way

% --------------
hfig = figure('Position',[200 200 800 600]);
hax1 = axes('Position',[0.1 0.6 0.8 0.3]);
plot([0:.1:10],sin([0:.1:10]));
hax2 = axes('Position',[0.3 0.1 0.4 0.4]);
[x,y,z] = sphere(24)
axes(hax2);surf(x,y,z,'FaceColor',[0 0.2 0.8])
axis vis3d
%Now try to zoom on the sphere it takes over the plot
camzoom(hax2,3)
% --------------

Thanks.

Interesting. If your data is of the form z = f(x, y) you
may have to manually clip your data.

Two dockable figures may be sufficient?

hfig = figure('WindowStyle', 'docked');
plot([0:.1:10],sin([0:.1:10]));

hfig2 = figure('WindowStyle', 'docked')
hax2 = axes;
[x,y,z] = sphere(24);
axes(hax2);surf(x,y,z,'FaceColor',[0 0.2 0.8])
axis vis3d

Clicking "Top/Bottom Tile" in the top right gives a similar
layout.

Thanks for the response. However, I don't know how to
implement something like that in my case. The above was
just an example of what happens when zooming
I am actually doing something similar with the plots but in
a GUI created in GUIDE. And I don't think you can really
dock a figure into a window in a GUI. It would be nice
though to restrict the viewable area of the axis to a
specific location. Sort of like put the plot axes in a
frame so it could not move or spill over covering out
uicontrols.
The only thing I can think off is to build the GUI using
multiple figs(which I don't really want to do).
I have also attempted to restrict the data created (like you
mentioned) but still can't quite get the view I want without
using either zoom or camera commands which change the size
of the plot axis displayed on the fig.

Thanks for the input.

yeah, weird situation. What I would do, make a new figure
window for the 3d graph. You can add this to the opening
function

    hFig = figure;
    set(hFig, 'MenuBar', 'none', 'Toolbar', 'figure')

% create callback to prevent figure from being
% explicitly closed
    set(hFig, 'CloseRequestFcn', ...
   'guiServoLoop(''fig_CloseFcn'',gcbo,[],guidata(gcbo))');

    handles.figGraph = hFig; % add figure to handle list
    guidata(hObject, handles) % saves update to handles

then add the function

% --- Executes upon close request to graph window
function fig_CloseFcn(hObject, eventdata, handles)
    %do nothing

and add to your main figure's deletefcn or closerequestfcn
(not sure if it matters, I'm using the deleteFcn) the
following line
    delete(handles.figGraph)

otherwise I have no idea, gl.

Yeah, I don't think I have any other option but to create a
separate figure for the 3-d graph that I need to
zoom/explore since the plot axes keeps growing inside the
main GUI window.
Thank you for the tips. That should help me control the
extra figure a little better so the end user doesn't close
it by mistake,

Thanks Again.

I have the same problem, but creating a new window is NOT an
option for me. I need to zoom/explore a 3-d graph inside a
panel of a GUI.
A similar problem happens if the graphic is an histogram or
a bar graphic (only when the parent of the axes is a panel
the graphic grows all over the panel, it is interesting that
this doesn't happen if the parent is a figure).

For example, using Ben's example:
Zoom this is ok
hfig = figure('Position',[200 200 800 600]);
hax1 = axes('Position',[0.1 0.6 0.8 0.3]);
plot([0:.1:10],sin([0:.1:10]));
hax2 = axes('Position',[0.3 0.1 0.4 0.4]);
x = 1:1:100; y = 100*rand(1,1000);
axes(hax2);
hist(y,x,'FaceColor',[0 0.2 0.8]);

But, zoom this and you'll see what happens.
hfig = figure('Position',[200 200 800 600]);
panel = uipanel('position',[0.05 0.05 0.9 0.9]);
hax1 = axes('Position',[0.1 0.6 0.8 0.3],'parent',panel);
plot([0:.1:10],sin([0:.1:10]));
hax2 = axes('Position',[0.3 0.1 0.4 0.4],'parent',panel);
x = 1:1:100; y = 100*rand(1,1000);
axes(hax2);
hist(y,x,'FaceColor',[0 0.2 0.8]);

I am using Matlab 7.1.0.246 (R14) Service Pack 3

I found a workaround on a website. Add the line:

zoom on;

after you plot the data. Now you can zoom on every plot.

The problem is when you zoom on the histogram because it
becomes bigger than the axes area (taking up all the panel)
and the same happens when I try to zoom a 3D graphic. I
don't know how to control the zoom for a 3D plot inside its
axes.
